Definitions

  • the invention relates to a method and an apparatus for detecting deposits on surfaces of moving machine parts of paper machines.
  • waste papers with functional coatings and waste paper from household-based detection contain increasingly foreign substances, which must be separated before re-paper production.
  • coarse dirt foreign materials such as wood, stones, metal, plastic, glass and garbage are found, which are separated and disposed of by mechanical separation processes at the beginning of the stock preparation process.
  • films, wet-strength papers and insoluble barrier coatings in waste paper which should be separated as possible without heavy crushing. This is preferably done in a coarse sorting directly after the material resolution.
  • the object of the invention is to provide a method and a device by means of which an early detection of sticky deposits on rollers, cylinders, clothing or the like is possible in a simple and secure manner.
  • the deposits are recognized when they actually occur. This makes it possible, in particular, to avoid an overdose of auxiliaries which should avoid later sticky deposits. Furthermore, the formation of deposits can be detected in good time so that expected damage to the paper machines or quality impairments of the paper produced can still be avoided. It is thus possible to detect sticky deposits beginning at an optimum point in time or at an optimum location and thus be able to take corresponding countermeasures in an efficient manner.
  • the object is further achieved by a device having the features mentioned in claim 6. It is particularly preferred if at least two acoustic transducers are present, which are arranged in particular over the width of a paper web to be produced.

Abstract

L'invention concerne un procédé et un dispositif de détection de dépôts sur des surfaces de pièces en mouvement de machines à fabriquer du papier. Selon l'invention, des vibrations acoustiques générées par les pièces de machine en mouvement sont détectées et les vibrations détectées sont évaluées pour déterminer la présence de dépôts sur les pièces de machine.
